PLATE No. 117. A large plant at Huntley North, Victoria, for distilling 

 the " Mallee " species. The two digesters, built of wood, were 

 7 feet 6 inches deep, by 5 feet 6 inches in diameter, and sunk in 

 the ground. A large tubular boiler supplied the steam, the pressure 

 being 15 to 20 pounds. The oil was rectified by steam. (Mr. J. M. 

 Hodgson.) 



PLATE No. 118. A Victorian distilling plant for the production of 

 Eucalyptus oil. Each of the four digesters was of 2,000 gallons 

 capacity. (Messrs. J. Bosisto & Co.) 



PLATE No. IIQ. A distilling plant at one time working at Punyelroo, 

 on the River Murray in South Australia. The digesters, one of 

 which is shown in the picture, had a capacity of between 4,000 

 and 5,000 gallons. One of them was a brewer's fermenting vat, 

 and the other built of pine, with the fittings. of copper. (Messrs. 

 Faulding & Co.) 



We have selected this series of plates as they give a very good summary 

 of the several methods employed in the production of Eucalyptus oil in 

 Australia. In an undertaking of this character, where some hundreds of stills 

 of one kind or another are in operation, it is to be expected .that a con- 

 siderable diversity in general ideas will be evident, but we think the range of 

 stills here illustrated is sufficiently comprehensive to cover the majority of 

 those employed in the industry.
